I'm not sure if this would be better posted in A&N, but as it has something to do with whirlybirds i thought that here might be the best starting place.
My father seems to remember back in the 70s an evening, possibly summer, where there was a succession of fast flying helicopters over southwest London, almost as though there was a chase going on. He thinks that he remembers reading in the papers that one had been stolen and the others were giving chase, but as it's a while back, his memory is vague. If only aircraft were racehorses, then it would all be razor sharp in his brain
Perhaps some of you might remember this event and/or know the participants that could shed some light on this mystery memory. I would imagine that it involved Bell JetRangers, as these were the cool steeds of the time.
